Abstract

PURPOSE:To make retrieval efficient by assigning priority to optional retrieval item data to specify the data and retrieving required picture data in accordance with the priority at the retrieval of picture data. CONSTITUTION:Plural medical picture data are stored in a file 1 together with retrieval item data such as addresses indicating their storing positions, patient names, dates disease names. These retrieval item data are written in a storage part 26 of a retrieving device 2 and the priority order of an optional retrieval item and data of the retrieval item are inputted from a keyboard 3 and stored in memories 20, 24 respectively. When ''1'' is set up in a priority counter 22 and the number is compared with the priority of the retrieval item in the memory 20, the address of the memory 24 is specified by an address generator 25, the retrieval item data (name) is outputted and the data (name) of the leading address of the memory 26 are outputted from an address generator 27 and compared by a comparator 28 if said priority orders coincide with each other. The generator 27 is successively updated and all names are compared, and at the coincidence of the name, the file data are outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an image data retrieval method and apparatus.

BACKGROUND OF THE INVENTION Recently, medical images have been filed using computers as part of medical systems, and are used for medical history management and the like. In such a medical image filing system, each image data usually includes address data indicating its storage location and search item data such as the number of bales, such as patient name, gender, date of birth, consultation date, disease name, site, and attending physician. etc. are recorded in the file section along with other data.

Conventionally, as a method of searching for desired image data in such a 7A/I ring system, data for each item is manually entered according to a preprogrammed order of search items, and all search items are searched sequentially from the first search item. A data matching method is used. However, in this method, the order of search items is fixed, and desired image data is searched by matching all search item data using the sequential search method, which has the disadvantage of poor search efficiency and time.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a search method that solves the above-mentioned problems and allows desired image data to be searched for efficiently and in a short time.

Furthermore, another object of the present invention is to provide a search device suitably configured to implement such a search method with a simple configuration.

Summary of the Invention The present invention, when searching for desired image data from a plurality of image data recorded in correspondence with a plurality of search item data, specifies arbitrary search item data with priority and specifies the specified search item data. The present invention is characterized in that desired image data is searched according to the priority order.

Furthermore, the search device of the present invention includes a main storage section that reads all search item data for all image data from a file section that records each image data together with a plurality of search item data and address data, and a main storage section that reads all search item data for all image data. and an input section for inputting search item data and its priority order, and detects address data for desired image data from the main storage section according to the manually-generated search item data and its priority order, and retrieves the desired image data from the file section. It is characterized by being configured to search for data.

Embodiment FIG. 1 shows the configuration of an example of a main part of an image file device embodying the present invention. In this example, medical images are filed, and 1 is a file section in which a plurality of medical image data are recorded together with address data representing each storage location and search item data such as patient name, date of birth, disease name, body part, etc.; Reference numeral 2 denotes a search device for searching desired image data from the file section 1, 8 a keyboard, and 4 a file controller, each of which is connected to a bass line 5.

FIG. 2 is a block diagram showing the configuration of an example of the essential parts of the search device 2 shown in FIG. 1. As shown in FIG. This search device 2 includes a memory 20 that stores priorities of arbitrary search items;
An address generator 21 for sequentially reading out the contents of 0, a priority number column 2□2, and a priority order number for counting the priority order. Kaur, 2
□. A comparator 23 that compares the output with the output of 7 and 20, a memory 24 that stores arbitrary search item data, an address generator 25 that sequentially reads the contents of this memory 24, and all search item data for all image data. , an address generator 27 for sequentially reading out the contents of the memory 26, a comparator 28 for comparing the output of the memory 26 and the output of the memory 24, and a control section 29 for controlling the operation of each of these sections. equip

Hereinafter, a boot chart showing the operation of this embodiment as shown in FIG. 8 will be explained. First, the memory 20 is stored under the control of the file controller 4.
The priority order of any search item is written in the memory 24 according to the input from the keyboard 8, and the data of the search item is written in the memory 24 according to the input from the keyboard 8, and all the search item data for all the image data in the file section l is written in the memory 26. After writing in address order, control is transferred from the file controller 4 to the search device 2. In this example, each image data is named
It shall be recorded in file section 1 along with four search items: date of birth, disease name, and body part, and each search item J will be recorded in J-1.
is the name, J-2 is the date of birth, J-8 is the disease name, and J-4 is the body part, and all search item data for the desired 19 image data to be searched is input into the memory 24,
In the memory 20, it is assumed that the priorities for the sequential search items J-1-4 are specified as 11 for name, 2 for disease name, 8 for date of birth, and 4 for body part.

In the search device 2, first, the control unit 29 resets each address generator 21, 25, 27, and sets the priority counter 22 to 11, that is, I-1.

The comparator 28 updates the value of the address generator 21 until the output of the memory 20, that is, the priority of the read search item J becomes equal to the value of the priority counter 22.
When these values match, the address generator 25 specifies the address of the memory 24 that stores the data corresponding to the search item J (name), and outputs the search item data (name) to the comparator 28. , the output of the address generator 27 is set to the start address of the memory 26, and the search item data (name) stored at the start address is outputted to the funparator 28. Comparator 28 sequentially compares the output of memo 24 with all the names in memory 26 while updating the contents of address generator 27.

Here, there are the following eight cases in the comparison results of the filter plate 28.

■When there is only one matching data.

■When there is no matching data.

■When there is multiple matching data.

In the case of O above, since the matching search item data corresponds to the desired image data, a search using one or more search items is not performed, and a file is searched based on the address data corresponding to the search item data. The controller 4 searches the file section 1 for the corresponding image data, displays this together with all search item data on a display device (not shown), and ends the search.

In addition, in the case of ■ above, that is, if there is no matching name due to an input error, etc., the value of the priority counter 22 is +
1 to I-2, and similarly searches the memory 20 for the search item J-a (disease name) corresponding to the priority I-2, and generates the address of the memory 24 that stores the data corresponding to that item. The patient 25 similarly searches the memory 26 for data matching the disease name data.

Here, if there is one matching data, display the corresponding image data along with all the search item data in the same way as in case ① above, and if there is no matching data, proceed as follows in the same way as above. Search the contents of the memory 26 using the data of the search item "item + J-21 date of birth" according to the priority order (I-8) of Then, the image data that matches the data of the next priority search item is searched from the group of image data having the matching data.

Furthermore, in the case of (■) above, that is, when there are a number of image data for the same patient, or when there are patient names with the same surname and names that cannot be identified, search item data for a group of image data that has the matching data is searched. The accumulated address of the memory 26 is extracted and stored, and the next disease name data of priority level I-2 is outputted from the memory 24 in the same manner as in the case (2) above, and this disease name data is output under the control of the stored address. The converter 28 searches for image data having title data that matches the data from the group of image data extracted above. Here, if there is one matching data, the corresponding image data is displayed together with all of its search item data in the same way as in the case of ① above, and if there is no matching data, the extracted search item data is displayed from the above ① In the same way as in the case of , extract items that match the search item data of the next priority, and if there are multiple matching data and cannot be identified, similarly extract a group of image data that has the matching data. The search item data is further extracted, and the data matching the search item data of the next priority is searched among them.

In the above sequential search operation, when the priority number exceeds the maximum value or when the search item J exceeds the maximum value,
In this example, it means that the data to be searched does not exist in the file, so an error message is displayed.

As described above, since the search items are prioritized, there is a greater possibility that a desired image will be identified through a search using search items with a higher priority, and therefore the overall search time can be shortened.

Furthermore, since the priority order can be specified arbitrarily, the optimum search can be performed in a short time according to individual requirements and usage. For example, it is possible to quickly and accurately obtain the medical history and treatment history of any patient, as well as statistical data on all patients.

Note that the present invention is not limited to the above-mentioned example, and can be modified or modified in many ways.

For example, the number of search items to be input does not necessarily have to be the total number of search items recorded for each image data, and may be less than that. In this case, if there is a plurality of image data that match the data of an arbitrary search item entered manually, all the search item data for each image data are displayed sequentially or in multiples along with the image data as necessary, and the operator selects the desired search item data. It is sufficient to select four items that do not correspond to the image data and display the image data. In addition, in the file section l, if image data and search item data are recorded in separate areas, for example, corresponding to different recording media, the search item data is recorded in the area shown in FIG. It can also be used as memory 26.

Furthermore, the present invention can be effectively applied not only to the above-mentioned search for medical image data but also to searches for other data information.

Effects of the Invention As described above, in the present invention, since search items are prioritized, desired image data can be searched for efficiently and in a short time.
